I am a frequent flyer with American Airlines and that means I spend a lot of time on MD-80s. Which, I have never really grown tired of flying on. I love the aircraft, and believe it is far more comfortable than an A320 or 737! Nonetheless, variety is the spice of life. Personally, I would like to fly on a Boeing 717 to do a little comparisan to its older brother.

I have flown the 737-300/700/800 and 757-200 this year.
all up i have flown 727-200, 737-200/300/400/700/800, 747-300/400, 757-200 and 767-200/300, A320-200 and A321, Fokker 50, DC9.
I would love to fly A330 and A340 and the 777

from the inside of the passenger cabin, all aircraft from any one airline often look pretty much the same.
Same seats, same FAs, same food (or what passes for it sometimes).
Only real difference is the size of the overhead lockers and the number of seats fitted.

Only differences would be aircraft used on intercontinental routes, which usually have better seats to cater to the fact that the passengers will be in them for a far longer time, and aircraft slated to be retired soon (which may well not have been upgraded with the latest new cabin to save money).
But even then, there is often little difference between types within an airline.

I travel a lot for work and most often fly Continental. I love them but the 737 is getting a little old. It always seems like I am on one (-300, -500, -700, or the -800). I actually have never been on one of the -900's yet, but that will not excite me much since I suspect the interiors and look are all the same.

I actually that did already flown on B737-800/900 into Continental Airlines from May 2002. That was did flown to PHX flight with stop into IAH. I do like flying on B737-700/800/900 for myself. Well, talk ya later!

I never get tired of the 717. I have flown on the 717 eight times, and all flights were wonderful. I flew on 2 DC9s in 1999. and I flew on 2 A320s with jetBlue last month. I just want to get on N77014 though while it is still in Peter Max Scheme.

I tried so hard to book my trip to MCO through ATL on a 777 or MD-11 but it was over $100 more and didn't work out with my schedule in MCO. I think I'll use my Skymiles to go to France next fall, then I'll have a chance on the 777. Does AF use a 747 to ATL as a code share? Maybe I can kill two birds with one stone!

Fully 1/4 of all my segments lifetime have been on a US Air (ways) 737-400, and about 1/8 of my segments lifetime have been on a US Air (ways) 757-200, most of those segments in the past two years or so...Im getting a little tired of them, but as I have little control over the travel planning in the house, I cant really complain...

95% of the time I am either on an MD-80 or 757. I am starting to get a little sick of them, the irony is that I am flying on a 757 for 4.5 hours next week. I don't have much control at all over the reservations in my house, so there isn't much I can do.

I've flown on most aircraft types. For some reason though I've never managed to board a 777 so that's one I'd like to try someday.. Also I've yet to fly a Bae-146 which is another... Of course it would be incredible to fly the Concorde.. and I think an IL-86 and IL-96 would be an interesting change too... It seems I'm always on a 767, A320 or A330 when I go somewhere which are nice but it's become a bit monotonous.
